Technical Field

The invention belongs to the technical field of agricultural mechanical equipment, and particularly relates to a ground-grabbing tooth-type roller power soil-breaking rake.

Background

The tractor pulls the seeder seeding, drives cylinder power hack harrow rotation simultaneously, and first rake shaft sprocket passes through the seed metering of chain drive seeder, the rotation of row's fertile sprocket and sows, spreads fertile, and second hack and suppression soil moisture conservation. The roller power soil-breaking harrow without the ground-grabbing teeth is partially contacted with the ground when the ground is uneven, so that the contact area of the roller power soil-breaking harrow and the ground is insufficient, the roller rotates insufficiently or slips and cannot rotate, the roller chain wheel cannot drive the seed and fertilizer discharging chain wheel of the seeder to rotate normally for seeding and fertilizing, and the seeding and fertilizer-spreading quality of the seeder cannot be guaranteed.

Disclosure of Invention

The invention aims to provide a ground-grabbing tooth type roller power soil-breaking harrow, which aims to solve the problem that the sowing quality and the fertilizing quality of a sowing machine are influenced because a roller does not rotate sufficiently or slips and does not rotate due to uneven land in the sowing operation of the conventional roller power soil-breaking harrow.

The invention relates to a ground grabbing tooth type roller power soil breaking harrow, which aims to prevent the roller power soil breaking harrow from rotating insufficiently or slipping and not rotating, and ground grabbing teeth are welded at the connecting part of a harrow wheel radial plate and soil breaking steel bars. Tractor traction seeder seeding drives simultaneously and grabs when tooth-like cylinder power hack harrow rotates, grabs the tooth and inserts in the soil, makes and grabs tooth-like cylinder power hack harrow and evenly rotates, can not lead to grabbing tooth-like cylinder power hack harrow rotation not enough or not rotating of skidding because of the land unevenness, the seeding of guarantee seeder, the quality of fertilizing.

In order to solve the above problems, the technical scheme provided by the invention is as follows:

the utility model provides a grab tooth-like cylinder power hack harrow, it includes frame, harrow axle, sprocket, chain and cylinder, cylinder movable mounting is epaxial at the harrow, and sprocket, chain are installed in harrow axle one end, and the chain drives the sprocket and rotates, and the sprocket drives the harrow axle and rotates, and the harrow axle is installed on the frame, characterized in that: the roller consists of a rake wheel radial plate, soil crushing reinforcing steel bars and ground grabbing teeth, wherein the soil crushing reinforcing steel bars are arranged on the rake wheel radial plate, and the ground grabbing teeth are longitudinally arranged at the connecting part of the soil crushing reinforcing steel bars and the rake wheel radial plate.

The invention has the beneficial effects that: simple structure, excellent in use effect, under the condition of land unevenness, guarantee that cylinder power hack harrow does not skid, evenly rotate, guarantee power take off is stable, the guarantee quality of sowing, fertilizer.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings.

As shown in the attached drawings 1 and 2, a ground-grabbing tooth-type roller power soil-breaking harrow comprises a frame 1, a harrow shaft 2, a chain wheel 3, a chain 8 and a roller 4, wherein the roller 4 is movably mounted on the harrow shaft 2, the chain wheel 3 and the chain 8 are mounted at one end of the harrow shaft 2, the chain 8 drives the chain wheel 3 to rotate, the chain wheel 3 drives the harrow shaft 2 to rotate, and the harrow shaft 2 is mounted on the frame 1, and is characterized in that: the roller 4 consists of a rake wheel radial plate 6, soil crushing steel bars 7 and ground grabbing teeth 5, wherein the soil crushing steel bars 7 are arranged on the rake wheel radial plate 6, and the ground grabbing teeth 5 are longitudinally arranged at the connecting part of the soil crushing steel bars 7 and the rake wheel radial plate 6.

Further, the cylinder 4 include four rake wheel radials 6, twelve hack reinforcing bars 7, twenty-four teeth 5 of grabbing, four equal distances of rake wheel radials 6 are arranged, twelve hack reinforcing bars 7 equipartition ground welding is on four rake wheel radials 6, the tooth 5 of grabbing on the same rake wheel radials 6 is the junction of interval installation at hack reinforcing bars 7 and rake wheel radials 6, grab tooth 5 of installing at the junction of a spoke 6 and hack reinforcing bars 7 promptly, and grab tooth 5 and hack reinforcing bars 7 and be 90 right angle welding together, the installation is grabbed ground tooth 5 and can be effectively worked like this, improve the ability of grabbing of cylinder 4, grab tooth 5 staggers the installation on two adjacent rake wheel radials 6.

Furthermore, the soil breaking reinforcing steel bars 7 are welded on the two adjacent rake wheel radial plates 6 at the inclination of 10 degrees, and the inclination of 10 degrees of the soil breaking reinforcing steel bars 7 arranged on every two adjacent rake wheel radial plates 6 is opposite, namely the soil breaking reinforcing steel bars 7 are in a continuous S shape, so that the strength of the roller 4 can be enhanced, and the distribution of the ground grabbing teeth 5 is facilitated.

Further, the length of the gripping tooth 5 is matched with the gap between the roller 4 and the frame 1.

Furthermore, the ground gripping teeth 5 are Y-shaped in the contact end with the ground.

Tractor traction seeder seeding drives simultaneously and grabs when tooth-like cylinder power hack harrow rotates, grabs tooth 5 and inserts in the soil, makes and grabs tooth-like cylinder power hack harrow and evenly rotates, can not lead to grabbing tooth-like cylinder power hack harrow and rotate not enough or skid and not rotate because of the land unevenness, the seeding of guarantee seeder, the quality of fertilizing.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
